Ivan Grokhotkov 19121e2f6f cmake: set IDF_VERSION_* variables at requirement expansion stage 
Currently IDF_VERSION_* variables are not available to the component
CMakeLists.txt files at the requirements expansion stage. This makes
it harder to write component CMakeLists files compatible with
different IDF versions.

Include version.cmake from the requirements expansion script, add a
build system test.

#
# Test the build system for basic consistency (Cmake/idf.py version)
#
# A bash script that tests some likely build failure scenarios in a row
#
# Assumes PWD is an out-of-tree build directory, and will create a
# subdirectory inside it to run build tests in.
#
# Environment variables:
# IDF_PATH - must be set
# ESP_IDF_TEMPLATE_GIT - Can override git clone source for template app. Otherwise github.
# NOCLEANUP - Set to '1' if you want the script to leave its temporary directory when done, for post-mortem.
#
#
# Internals:
# * The tests run in sequence & the system keeps track of all failures to print at the end.
# * BUILD directory is set to default BUILD_DIR_BASE
# * The "print_status" function both prints a status line to the log and keeps track of which test is running.
# * Calling the "failure" function prints a failure message to the log and also adds to the list of failures to print at the end.
# * The function "assert_built" tests for a file relative to the BUILD directory.
# * The function "take_build_snapshot" can be paired with the functions "assert_rebuilt" and "assert_not_rebuilt" to compare file timestamps and verify if they were rebuilt or not since the snapshot was taken.
#
# To add a new test case, add it to the end of the run_tests function. Note that not all test cases do comprehensive cleanup
# (although very invasive ones like appending CRLFs to all files take a copy of the esp-idf tree), however the clean_build_dir
# function can be used to force-delete all files from the build output directory.
# Set up some variables
#
# override ESP_IDF_TEMPLATE_GIT to point to a local dir if you're testing and want fast iterations
